Please Whitelist This Site?

I know everyone hates ads. But please understand that I am providing premium content for free that takes hundreds of hours of time to research and write. I don't want to go to a pay-only model like some sites, but when more and more people block ads, I end up working for free. And I have a family to support, just like you. :)

If you like The TCP/IP Guide, please consider the download version. It's priced very economically and you can read all of it in a convenient format without ads.

If you want to use this site for free, I'd be grateful if you could add the site to the whitelist for Adblock. To do so, just open the Adblock menu and select "Disable on tcpipguide.com". Or go to the Tools menu and select "Adblock Plus Preferences...". Then click "Add Filter..." at the bottom, and add this string: "@@||tcpipguide.com^$document". Then just click OK.

Thanks for your understanding!

PPP Feature Protocols

PPP is the standard for data link layer connectivity over serial links because its core protocols provide a solid operational foundation, as we saw in the previous section. However, PPP's popularity is based not just on its highly capable link establishment and management features. It also has a number of very useful features that provide important security and performance benefits to network users.

In this section I describe the protocols that implement several of the most common "extra" features in PPP. I begin with a discussion of PPP link quality monitoring. I describe the sets of protocols used to configure and implement data compression and data encryption. I then discuss the PPP Multilink Protocol (MP, MLPPP), which allows PPP to bundle multiple low-speed links into a single high-speed link. I also cover the BAP and BACP protocols, which are used to manage the operation of Multilink PPP.
